SUPER COOL INVERT SHENANIGANS

Sea urchins have modified mouth parts on the underside of their bodies called an Aristotle’s lantern. The lantern is made up of tooth-like plates that scrape up bits of food like algae, as seen here.

We specifically don’t scrub the algae in this habitat for the urchins, and I see them on the walls all the time, presumably getting a tasty meal. But I had never seen it in action before last week! Invertebrates are such cool little aliens!

Happy Halloween from our little sea monster! The animal training department let us borrow their festive decorations, and it was kind of the greatest thing in the whole entire world. Still not sure if this was more enriching for the octopus or the aquarists!!

Did you know? When octopuses are caught in the act of moving rocks and destroying the hard work of their aquarists, they drop everything and slowly back away like nothing happened.

  • Hufflepuff: I've planned out our day, and I think it's going to be a lot if fun!
  • Ravenclaw: I want to go to the aquarium.
  • Hufflepuff: That's not on my planner...
  • Ravenclaw: But I want to learn about the jellyfish and how they eat.
  • Hufflepuff: Maybe another day?
  • Ravenclaw: And you can pet the stingrays.
  • Hufflepuff: Okay, let's go pet some stingrays.
